A NEW OPTIONAL EXTRA
Take a side path.
Choose Streets + Side Paths to collect routes between the streets too. Side Paths has its own progress.
Streets remain the main game. Municipality completion and street achievements still count streets only.
50 new ways to achieve.
Discover your first path, collect streets with different initials or explore three municipalities in a day. New achievements reward streets, Side Paths, familiar walks and new places.
Keep exploring across borders.
Collect streets in several municipalities during one outing. Download neighbouring maps in advance and see every municipality you visited in your walk summary.
See your discoveries more clearly.
Clearer area and Finland maps bring your progress into view. Street detection, walk recording and settings have been refined so you can focus on your walk.
Keep a backup of your own.
From version 2.0, Katujahti's own online backup is removed. Your progress stays on your phone. Save a file backup too.

THE KATUJAHTI STORY
From a family game to streets across Finland.
Katujahti started with Johanna’s idea and the family’s walks. With help from testers, it grew into a game for all of Finland.
- The first streetsJuly 2026
What if we walked them all?
Johanna read in Helsingin Sanomat that Pentti Arajärvi had walked every street in Helsinki. She discussed the idea with her husband Jussi, and it became a walking game for the family. Katujahti marked the streets they had walked on a map, making it easy to choose new ones for the next walk.
- All of Finland28 July 2026
From home streets to 308 municipalities.
The game grew to cover Finland. Over 224,000 streets, local areas and three languages. Downloaded streets could be collected offline too.
